It's important to remember that not every American who voted for Drumpf was voting because they themselves are racist, sexist, anti-LGBT etc. It is very easy to lump all those voting Republican as being privileged white folk, uneducated rednecks or self serving elitists, when the government has repeatedly ignored cries for help from the rural communities outside the state cities over the last number of decades.
Rural areas that used to have a major business like factories, farms, oil refineries, mines which are now shut have taken massive recession beatings and are in deep seated poverty. Their main sources of income and trade are gone but there's been lacking support from any administration to get them back on their feet. They don't get the same levels of education or maintenance those in urban areas do, hence unsurprising when it turns out they're simple minded or ill educated.
All the attention and funding goes into the densely and diversely populated cities, particularly the central metropolitan districts, where the majority of businesses are now. Gentrification and globalisation is far more profitable in our shiny, technologically advanced, affluent and culturally diverse side of the 21st century than localisation and providing realistic support to poor areas with lacking economies. So, it is no wonder that those out in the smaller towns and rural neighborhoods are disillusioned with the establishment and desire major changes.
And generally speaking, it doesn't help that in government (for the most part), those previously in charge have taken the powerful advantage to cut public spending and important laws/rights, increase taxes, privatise public sectors, take part in international wars and construct false narratives that vilify a certain class, a certain minority, a certain country for their own personal gains (read: wealth and control). Then of course, there's mainstream media which capitalises off the discontent and sensationalises the 'them vs us' narrative even further, creating the nationalist populism we're seeing now, scapegoating innocents whilst ignoring the actual government corruption.
It all feeds back into itself like a horrendous socio-political economic ouroboros and thus creating a situation where neo-fascism has returned for a mainstream encore in the western world. All we can do is give a sarcastic round of applause to neo-liberalism and any elected official in any western government (right and left) whose deplorable decisions since 1945 have trickled down into the year we call 2016.
So, yeah, I do understand why Drumpf has been voted in. Politics is treated as a money making business now so for an elitist businessman, having this level of wealth and control in a first world country is going to be an incredibly lucrative venture. If the government aren't going to listen to or help the citizens that they allegedly serve then getting in this sociopathic and fascist thinking buffoon with no political experience is a wake up call to the horrifying realities of what we thought to be a progressive 21st century.
Can't wait for the next radical left uprising though, it's gonna be a wild revolution
